I'm trying to setup my website to have music score and audio previews so my customers can see and hear the music and the score will turn pages as the music progresses, before they purchase. I found a program that will convert the powerpoint slideshow to .html and I'm using an iframe inside of a container but am looking for some input on what would make it look better. http://www.laniermusicservices.com/gbsag.html
Here is my iframe and my container and html element settings

<iframe
frameborder="0"
width="1100"
height="800"
src="amazing_grace/amazing_grace.html">
</iframe>

The html element settings
Block Display
Width 100% Min 1100 px Max none
Height auto Min 800 px Max none

The container settings
Block Display
Width 100% Min 1100 px Max none
Height auto Min 700 px Max none
Margin left and right auto - to center it

Any help would be appreciated.
Thanks
